Why Your Conservatory Overheats
Traditional conservatory roofs – often made from polycarbonate or basic glass – act like a greenhouse in the summer. The sun’s rays pass through but get trapped inside, quickly pushing internal temperatures above 30 °C. This problem is especially common in south-facing conservatories across Norwich, Norfolk, Suffolk and Cambridgeshire where long summer days and minimal ventilation combine to make the room unusable during warm months.
Poor insulation in older roof systems also means heat builds up fast but escapes slowly, turning your conservatory into a sweltering, stuffy space. If blinds and fans aren’t cutting it, the root issue is likely the roof.
How a Replacement Roof Fixes It...
Swapping out your existing roof for a solid tiled or hybrid Warm Roof transforms your conservatory into a true year-round room. These high-performance systems include multiple layers of insulation, internal plastered ceilings, and integrated ventilation – all designed to reflect solar heat and maintain a stable indoor temperature.
In Norfolk, Suffolk and Cambridgeshire homes, we often install lightweight solid roofs finished in slate-effect tiles that match the main property, with added rooflights to keep the room bright without overheating.
The result? A space that stays around 20–22 °C even on hot July days.

What It Costs – And How Quickly We Can Fit It
Most roof-only replacement projects fall between £15,000–£27,000 + VAT, depending on size, roof shape, and extras like rooflights or internal spotlights. Compare that to a complete conservatory replacement (including brickwork) and you can account for at least 2x the cost of a roof-only replacement. We offer finance options to help spread the cost.
Lead times can be as quick as 4 weeks from quote to completion, with most installations taking just 2–4 days on-site – no need to rebuild the walls or base.
